Answer : 3. "Chalk powder "
Explanation :
Chalk powder, which primarily consists of calcium carbonate, is relatively insoluble in water. While it can react very slowly with water over time to form soluble calcium bicarbonate, the solubility of chalk powder in water is extremely low, making it effectively insoluble for most practical purposes.
